description A field emission lamp, capable of increasing the number of electron emitting points thereof, and of increasing the uniformity and the intensity of the light output therefrom by installing a lens unit is disclosed. The field emission lamp comprises: an outer shell having an inner surface, an anode portion formed on a portion of the inner surface of the outer shell, a cathode portion surrounded by the outer shell, a phosphor layer formed on a portion of the anode portion, and a lens unit disposed adjacent to the inner surface of the outer shell where the anode portion is not formed. Wherein, the phosphor layer generates light due to the bombardment of the electrons, the light passes through the lens unit and the inner surface of the outer shell where the anode portion is not formed, and outputs from the field emission lamp.
